UNITED STATES PATENT OFFICE.

JOSEPH E. FISKE, OF JAMESTOWN, NEW YORK.

BOLTlNG-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 276,169, dated April24, 1883. Application filed September 16 1882. (No model.)

To all whom it may concern Be it known that I, JOSEPH E. FIsKE, ofJamestown, in the county of Chautauqua and State of New York,haveinvented certainnew and useful Improvements in Flour-Bolts; and Ldohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others'skilled in theart to which it appertains to make and use the same, reference being badto the accompan ying drawin gs, which form a partof this specification.

The object of my invention is make a simple and efficient device to jaror rap the frame of a bolting-reel or rotary flour-bolt in such a mannerthat the bolt-cloth will at all timessift the flour without theliabilityto clog; and the invention consists in devices hereinafter described,and shown in the accompanyingdrawings, in which- Figure 1 is a planview; Fig. 2, a sectional view on line X X, Fig. 1. Figs. 3, 4, and 5are detail views enlarged.

A represents a bolting'reel frame, and B the bolting-cloth, made andapplied in the usual manner.

Flour-bolts as commonly made and used are very liable to have thebolt-cloth fill up or clog in the meshes, and to overcome thisdifficulty 1 securely fasten a short extension-arm, C, to each arm ofthe bolt-reel, as shown in Figs. 1, 2, and 4, and these arms I generallyround at the outer end and put on a ferrule to prevent their splittingand let the end of the timber project a little beyond, so that the woodbears against the spring D and receives the blow from the hammer Y atthe end, and the wood deadens the sound without any other appliance. Thespring I) may be of steel or wood, as desired, and has at the end aniron hammer, made by the offset, as shown at 3 Fig. 5. The spring-handleis securely fastened at one end of the frame of the flour-bolt, havingthe hammer end extending out so that the short extension-arms O G willstrike against the spring diagonally and press it back, and as they passthe hammer end a sudden blow is given these arms as the reel revolves,and this succession of blows jars the meshes of the bolt-cloth so thatthey are kept clear of flour. The spring-hammer is put on so as tostrike eudwise of the reel and always at the highest point, and istherefore more eflicient than a lower side blow would be. Tilespring-hammer is held at any desired position by means of theregulating-screw E and yoke b, the

spring passing through theyoke ato, Fig. 3, the

object being not only to set up the spring-hammer to give aheavier blow,when desired, butto draw the hammer away from the extensionarms of thereel when not in use.

I am aware that devices for rapping boltreels have been used; but

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the bolt frame or reel,

the extensions rigidly secured to the arms of said reel and extendingoutwardly therefrom, the spring-hammer, a support to which said hammeris secured,,the yoke, and the regulatin g-screw, substantially as shownand described, and for the purpose set forth.

2. In a flour-bolt, the combination of arms 0 O, hammer Y, spring-handleD, a support to which said handle is secured, screw E, and yoke b, allarranged to operate substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of .two witnesses.

JOSEPH E. FISKE.
